System-Specific DDR5 Kit

This OWC kit provides 64 GB of DDR5 memory in two 32 GB SODIMM modules. It is built for the Lenovo ThinkBook 14 G6 IRL and 16 G6 IRL laptops. The modules run at 5200 MT/s with CL42 latency at 1.1 V.

Dual-Channel Upgrade Path

The 262-pin form factor fits the factory slots in the compatible ThinkBook models. Two ranks per module (2Rx8) populate both channels for maximum bandwidth. Non-ECC unbuffered operation matches the platform requirements.

Sustained Workload Stability

JEDEC-standard timings and voltage ensure consistent throughput during extended multitasking or large-file editing. The CL42 latency and 1.1 V power draw remain steady without thermal throttling. Buyers needing ECC error correction or higher frequencies must choose a different specification.

Questions about this item

Will the CL42 latency become the bottleneck during sustained heavy workloads?

The CAS latency is CL42 at 5200 MHz, which is the standard JEDEC timing for this DDR5 SODIMM kit and sets the baseline response time under load.

How much heat or power draw should I expect from these modules when running all day?

They operate at 1.1 V without a heat spreader, so power draw and heat output remain low, matching the standard DDR5 SODIMM thermal profile for thin-and-light laptops.

Does my ThinkBook need any specific BIOS version or firmware update before installing this 64 GB kit?

The kit is validated for the ThinkBook 14 G6 IRL and 16 G6 IRL and is designed to meet OEM specifications, so it works with the factory BIOS that ships on those models.
